In the UWB PPM bench, I'm a little bit confusing about the parameter setup for "DithersPerPPMBitOffset" and "DitherTime". I couldn't get a clear understanding even if I tryed my best to view the DesignGuide Document. Is there anybody who can give some explanation in details or provide some materials describing these parameter setup?

Among all of the parameters set for the "PPM_TX_Pulse_Generator", I would like to know which one corresponds to the shift introduced by the TH code and which one corresponds to the shift introduced by the PPM modulator. The relationship between them should be the shift introduced by the PPM modulator much smaller than the TH shift. From the description for "TStepsPerPPMBitOffset", which says "Length of offset between a value of 1 and 0 in a PPM modulated code", we could conclude that this parameter is supposed to correspond with the PPM modulator shift.
However, the TStepsPerPPMBitOffset is larger than the TStepsPerDither. Does per dither correspond to a chip?
Really I'm confused. Please help me.
